Abstract

L'invention porte sur un enroulement de détection pour un capteur de courant à interféromètre de Sagnac, l'enroulement de détection (14) étant constitué par une fibre optique (par exemple, une fibre Hi-Bi de polarisation filée) qui est configurée pour, lors de l'utilisation, transmettre un état de polarisation elliptique unique, l'enroulement de détection comprenant au moins deux boucles interconnectées (15 et 16 ou 26 et 27 ou 28 et 29). Au moins l'une des boucles est configurée pour, lors de l'utilisation, enfermer un conducteur de courant (11, 12 ou 25), et les boucles sont interconnectées de telle sorte que la lumière se propageant dans une première direction (23 ou 30) dans la première boucle se propagera dans une deuxième direction opposée (24 ou 31) dans l'autre, ou, s'il y en a plus d'une, dans chacune des autres boucles, grâce à quoi l'enroulement de détection produit une sensibilité minimale au mouvement de rotation. L'invention porte également sur une unité de détection (Fig. 5) qui incorpore l'enroulement de détection et sur un capteur de courant (Fig. 1) qui incorpore l'unité de détection.
